Story Highlights
After debuting during Fox Sports' coverage of the MLB All-Star Game last year, RF Wireless's new UmpCam system has been popping up across broadcasts on ESPN, Fox, and Apple TV during the opening two weeks of the season. Although similar systems have been used for baseball coverage in the past - both Fox and ESPN deployed similar systems on catchers and/or umps in the early 2000s - RF Wireless's system is the first that can be integrated into the line cut and properly shaded in the truck so that it closely matches the rest of the cameras in the broadcast.
Our goal was to avoid any disruption of the workflow in the truck and make it as feel like it is in time with every other resource, says RF Wireless President Rob Bunn, while putting a device on the umpire that was light enough and small enough so that he wasn't disrupted either.
Three Years of Development: Many, Many Rounds of Testing' MLB and RF Wireless have been developing the system - which features a small Marshall board-level POV camera, miniaturized RF transmitter, and housing customized to the type of mask the umpire is wearing - for nearly three years. MLB first approached RF Wireless about the concept after seeing the quality of the RefCam systems thatRF Wireless had developed for NHL coverage.
MLB came directly to us and asked if we would be able to do something similar [to NHL RefCam] on the umpire, says Bunn. The technology was pretty much ready to go, but we had to build something that was safe for the umpire and would work in that environment without disrupting them. What followed was many, many rounds of impact testing and lab testing.
RF Wireless and MLB tested the various iterations of UmpCam during games at the University of Lowell in Massachusetts. Broadcasters Fox and ESPN also provided input and encouragement throughout the development process.
RF Wireless created a custom camera-shading system for the UmpCam in-house to ensure that it looks as similar to the other cameras in the line cut as possible.

The only way we were going to do this is if we could figure out how to paint cameras correctly, says Bunn. We didn't want to just have another wearable POV camera that looked different from every other camera in the broadcast. Even though it isn't an exact match to the [broadcast] cameras, it's certainly a lot closer than anything else that I've seen.
He adds that going with a traditional RF transmission system akin to those used on wireless handhelds, cable-based cams, and other specialty cameras allows the UmpCam feed to be timed nearly perfectly with the rest of the broadcast cameras. As a result, the UmpCam can be used in the line cut - something a few directors have already done - in addition to being used for replays.
We spent so long developing the system, he says, because, if we weren't able to match the other cameras and sync with them while also making the umpire happy, this would have been just another fad camera that lasted a few games and then disappeared.

Home-plate umpire Bill Miller was the first to wear the UmpCam during Fox's 2022 MLB All-Star Game coverage, as well as on ESPN's White Opening Night broadcast on March 30. He wore the mask for four innings on Opening Night, and the umpire for ESPN's Sunday Night Baseball broadcast the following night wore it all nine innings.
I think the real secret to success has been our ability to work directly with the umpires, says Bunn. We learned from hockey that this can't just be a broadcast [tool] that we're attaching to an umpire or ref; it needs to be something that the umpires are comfortable with, first and foremost. They need to feel like we've listened to them, taken their feedback, and developed it into a solution that works for them on the field.
In terms of workflow, the broadcaster's video techs shade the cameras themselves in the truck. An RF Wireless tech is onsite to look after the receive site and monitor all the data back and forth. A second RF Wireless tech is on the field level to change out batteries periodically throughout the game and handle any issues that might come up with the umpire or the system during the game.
It has definitely come a long way, says Bunn. The first iteration looks very different from the iteration that has actually made it to the field. And we're already working on the next iteration, which, hopefully, we can roll out next spring.
Fox Sports on UmpCam: One of the Most Significant Additions to the Broadcast' An UmpCam view of a pitch during the Phillies-Rangers game on April 2
Fox Sports SVP, Field Operations, Mike Davies says that the biggest advantage of UmpCam thus far has been on replays, where it offers a new perspective that makes a replay package much more interesting.
We debuted the UmpCam for the All-Star Game last year, he notes. It was one of the most significant additions to the broadcast: not only sheer eye candy but a unique, dramatic perspective that all fans could get behind.
The idea of the UmpCam has been something we have been chasing since CatcherCam nearly 20 years ago, he continues. But all credit to UmpCam's development goes to MLB and RF Wireless, who led this iteration. They spent the time and developed the relationships to make this a reality.
